rllhe practical use of this invention will be obvious trom the drawings.`When the sashes are closed.` the parts are in the positionshown in Fig.QL The tongue 15er-u tends oyer the striking plat-ewhile the lockl ingmember Q abuts against the rear wall oli the support lO. Under thesecircumstances it it is attempted to raise the lowersash or lower theupper sash, the locking member 20 will bind against the rear wall l0 orany other suitableabutment, and will wedge and absolutely prevent anyrelative movement ot Ythe two sashes.y lt, now, however,` the lockingmember 20c, be shifted tov the dotted linef'position shown in Fig. i2,then the lower sash can be raised or the upper sash lows ered andas thisoccurs the tongue l will be lifted and eventually the tongue l5 and thelocking member will be shifted to the position shown in Fig. il,entirely free ot the lower sash, and the lower sash can then be raisedor lowered withincertain limits withoutA affecting the latch at all. Nowupon lowering the lower sash from the position shown in i tothat shownin Fig. 2, the projectingedge of the striking plate Q2 will strike theprojecting lug 1G and cause the tongue to rotate or tall over to theposition shown in Fig. 2, and as this occurs the piv otal support torthe locking member 2O will move upward and then :tor ard land as movesforward, the locking memberv 2G will saitt to the position shown in Fig.2, wedg` ing into place and the sashes will be locked fromrelativemovement. ll/hen the lockingl tongue l5 is disposer as shown inllig. 2, the lug l? will engage over the edge face of the striking plateand will bindy thereon and will thus positively prevent the window tromrattling. lt is to be understood that the striking plate 2:2 is widerthan the tongue 15 and that as it projects beyond the edge of, B alongits entireeiltent, it will prevent al line knife blade trom beinginserted between the meeting rails A and B to effect the lifting of thememberl 15 or of the lock ing member 20. rllhis makes thedevicethiet-proot from the outside.

ldlhile l have illustrated a construction which l have foundparticularly effective in actual practice, which may be cheaply made andwhich is easily attached to any make ot window sash, yet l do not ,wishto be limited tothe actual details illustrated as it is ob yious thatminor changes may be made in the'details without departing trom thespirit oiy the. intention as described in theappended claims.,

Having Ithus-v fully described my inyention, what l claim is:
